Sulphate solution

Method: 1. Firstly you need to need to measure accurately 0.50g of your copper sulphate solution into a 100cm³ beaker 2. Then add about 50cm³ of distilled water ensuring you continue to stir until crystals have dissolved. Then transfer the solution into a 100cm³ volumetric flask 3. Next rinse out the beaker with small amounts of distilled water and transfer the washings to the volumetric flask to ensure none of the solution is wasted affecting the end result. 4. Once the beaker is sufficiently washed

acetate. Introduction: An equilibrium constant for a solid substance that is dissolving in an aqueous solution is represented by the solubility product constant, where the concentrations of different ions from the solid substance (compound) are used to calculate the solubility product constant. If the solubility product constant vale is high then the substance is very soluble in an aqueous solution. The solubility product constant is denoted by Ksp, and for a common reaction: aA(s) ⇌ cC(aq)+dD(aq)T

spectrophotometer, we were able to measure the absorbance of Copper (II) sulphate with increasing dilutions. From this we were able to create a graph showing the concentration as well as the absorbance. The Beer Lambert Law is the linear relationship between the absorbance and concentration. This has a connection with the light behaviour as well because light behaviour effects the concentration and absorbance. The more concentrated that a solution is, the less light passes through it. Purpose This lab allowed

The force, which drives reverse osmosis (water leaving the solution side of semipermeable membrane), is the pressure of a solution combined with external added pressure. In the presence of additional pressure solvent molecules can move out of the solution at a higher rate than the rate of solvent molecules flowing into the solution. Under these circumstances the solute will eventually be concentrated on one side of the semipermeable barrier.

A heating bath is used in the laboratory to allow the chemical reaction to occur at an elevated temperature around 1000C. The beaker is a glass vessel which contains the chemical solutions for the purpose of coating. It is placed in the electroless bath where the chemicals are being heated up. The glass rod is used to stir the chemical where the magnetic stirrer is not necessary. The tongs are used to lift the bath after the coating is completed. Tri-sodium citrate and thallium acetate are the chemicals

42. For each of the following mixtures, explain whether it is a solution or a heterogeneous mixture. For the solutions, identify the solute and the solvent. a) Cloudy pond water – heterogeneous mixture, this is because it is cloudy, solute is dirt particles - in the water there is clay and humus. b) Apple juice - is a homogeneous solution, water is the solvent there are organic acids, sugars and gums c) Rain water – is a homogeneous mixture, rainwater is nearly a distilled water. The mixture is

Solubility Enhancement of Fenofibrate by Solid Dispersion Technique 1. Introduction: Oral route of drug administration is one of the preferable methods of drug delivery due to its convenience, ease of administration and a more effective medication system than other drug delivery systems in terms of patient’s compliance. However, not all drugs are of same solubility; some poorly soluble hydrophobic drug often generates certain complexities in formulation development as well as other clinical research

"Do different concentrations of solutions determine the mass of a potato?" Introduction: The way to get the full results of this lab was through the process of osmosis. Osmosis is the movement of water across a membrane into a more concentrated solution to reach an equilibrium. When regarding cells osmosis has three different terms that are used to describe their concentration. The first of these words is isotonic. Cells in an isotonic solution show that the water has no net movement and the amount
